I frequently have dreams of the exterior world working its way into my dreams example your alarm ringing for u to get up and it's Somone honking at u in ur dream. Well last night I had a dream that my arm was stuck in a vacum cleaner it sucked my arm up right to the shoulder when I woke up my arm was completely numb. I rubbed it intell the blood came back lmao my brothers face was priceless like wtf how did u do that lol
